AppsSamplingPackage

The sampling package for collecting installed apps and app usage.

Register it before you deploy a protocol that uses APPS or APP_USAGE:

SamplingPackageRegistry().register(AppsSamplingPackage());

Key points:

• Both measures only work on Android. On other platforms create returns null, so no probe runs.
• Registers Apps and AppUsage for JSON deserialization.

See also AppsProbe and AppUsageProbe, which do the collection.
